Who doesn’t love to experiment with iPhoneography? Here’s a super cool tip on how to turn your iPhone camera into a microscope with just a drop of water, as noted by Alex Wild over at Scientific American.
All you have to do is place a drop of water on your iPhone’s camera lens, and voila, you have yourself a DIY microscope or the perfect macro lens. The technique isn’t new, and has been used before by a research team at U.C. Davis. They tested the water droplet technique which forms a meniscus, and the subsequent curved surface would act like a magnifying lens, that enabled them to diagnose patient samples.
Here’s a sample image taken by Alex–the water acts so well you can even see the hairs of a honeybee:
I tested Alex’s idea and came up with the following picture of a toonie. Note the first image is the max I could get my iPhone 4S camera to focus. The next image is literally a macro shot of that same toonie, but with a water drop on the lens.
You can even see the typica of my fingerprint:
I took my pictures with the iPhone 4S on the edge of a flat surface screen side down. I placed a droplet of water on the lens, then slid the camera over so I could see the screen, and snapped the picture with the volume up button. I’m sure you can come up with other methods for your iPhone ‘water-graphs’.
As always, be warned when using water around your iPhone. Let me know how this little iPhone photography hack works for you!
